I’m changing a server with a bare metal installation with one ip to a new cisco sever with esxi with 3 vm’s, one of them is going to be a nat router to nat the traffic to the other 2 vm’s, is there a way to keep using one just ip ?
I don’t think so, you will need at least 2 one for esxi virtual network to communicate with your network and one for your nat router vm to distribute the traffic via NAT
In fact if your server has CIMC you will need another one to have a remote access to CIMC if you need to recover the server, but it’s not mandatory because you can always connect to CIMC through the console.

Description:
There is a domain name road.songyangxing.com which resolves to 172.20.12.79. Notice that the ip is private.
We build and run openwrt on Raspberry Pi 4 Model 4. We connect the WiFi lan which the openwrt generates.
Run the command ping road.songyangxing.com, it shows Ping can't find host road.songyangxing.com.
It's OK for pinging the domain name which resolves to a public ip. It's OK for pinging road.songyangxing.com when we change another router.
Question:
How could we let openwrt allow private ip domain name?

I want access to remote cassandra with one ip address. how can I change cassandra.yaml to block all ip address except ip that I want to connect?
On current Cassandra versions there's no way to block inbound connections. You can (and you must) enable authentication, but it seems that you want to block before Auth phase.

So I have started learning docker, and where better to start than with servers! Anyways, I started out trying to create a minecraft server. I managed to get it working on localhost, but is there any way to make it available to people outside of my own wifi?
You better get an EC2 instance (VPS) from AWS or any cloud provider and run your docker image in it.
The server will be available 24/7 and you keep your machine safe, it's bad to open ports on your computer for the external world.
You can get a free instance on AWS for one year

I'm working in a company xxx and due to Covid-19 we are all working from home.
When trying to connect Jenkins website I get from chrome :
This site can’t be reached
jenkins.xxx.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN
Connected to the internet via WiFi.
I have to be connected via VPN to enter Jenkins website.
When connected via mobile hotspot and VPN, the website works.
Working on Mac OS - Catalina.
Thanks ;)
I guess that your Jenkins server is not publicly accessible (which is good for your Jenkins server security). This is the reason why it works in the internal network (you are connected to this via VPN) and does not work when you are not connected via VPN.

I have a Virtual machine running within the Virtual Box. And now I need to access the port 25 of a IP address from the VM. The thing is I am able to do the "telnet url 25" outside the VM in my host machine, but I just can not do it within the VM, the error is "name or service not known". For the host machine, I dont have any firewalls. Any idea why
The VM can not resolve the URL cause a problem connection with the DNS server. After I replace the URL with a real IP address, it works!
